| 近些年来随着遥感技术的不断发展，在植被覆盖区的金属矿床的探查中，遥感植物地球化学方法得到了越来越广泛的应用。文章从理论、技术和应用三个方面对遥感植物地球化学方法的发展进行阐述，并指出目前存在的问题。其中使用定量化的手段提取植物地球化学信息是未来的必由之路。然而在定量化的过程中，光谱尺度效应和空间尺度效应是两个重要的影响模型精度的因素。针对这个问题，文章提出两种解决方案来减小光谱尺度效应的影响，然而这两种方法的可操作性以及可靠性还需要进一步探讨。最后，文章对遥感植物地球化学方法的发展前景进行阐述，并指出在以后定量模型的建立中可以引入支持向量机、投影追踪等机器学习的方法。 |

| With development of remote sensing technology in recent years remote sensing plant geochemical method has been widely used in the exploration of metallic deposits in the area with vegetation. In this paper is mainly expounded the development of remote sensing of plant geochemistry from three aspects of theory, technology and application and pointed out the existing problems. Quantitative extraction of plant geochemical information is the only way to take for remote sensing plant geochemistry in the future. However, in the process of quantification, the scale effect of spectrum and space are two important factors to influence accuracy of the model. To solve the problem, this paper proposes two solutions to reduce influence of the spectral scale effect while the two methods' operability and reliability need to be further explorated. Finally, this paper expounds the development prospects of the remote sensing plant geochemical method, and points out that in the future, support vector machine, projection machine, and other machine learning methods can be introduced for the quantitative model building. |
